Abstract: PURPOSE:To obtain a high mechanical strength, antifreeze resistance by forming the top and base of a tank of a radiator for a vehicle of resin composition formed by melting and kneading polyphenylene sulfide resin, polyphenylene oxide, etc., by injection molding. CONSTITUTION:In order to obtain the top and base of a tank of a radiator of resin using long life coolant(LLC) as cooling liquid whose strength does not decrease due to contact with high temperature LLC, resin composition formed by melting and kneading 100 pts.wt. of polyphenylenesulfide resin (PPS), 10-20 pts.wt. of polyphenylene oxide(PPO) and 50-400 pts.wt. of fibrous and/or nonfibrous filler is used by injection molding to obtain an object. As the PPS, a polymer represented by a structural formula (I) containing 70mol% or more or preferably 90mol% or more of repetition unit is used, and as the PPO, a polymer represented by a structural formula (II) is used.

Abstract: PURPOSE:To mold a superior blow hollow molded product of thermal shock properties and heat resistance by flow molding a polyphenylene sulfide resin composition composed of modified polyolefin, thermoplastic elastomer and a fiber-like and/or granular reinforcing agent. CONSTITUTION:A resin composition of superior blow molding properties without generating dry spots of glass fiber when an inorganic filler such as glass fiber or the like is blended by combinedly adding thermoplastic polyester resin and thermoplastic elastomer to a composition composed of PPS and specified modified polyolefin. It is preferable that PPS is deionized by cleaning by means of oxidization, hot water treatment or an organic solvent. The blending ratio of the resin composition is 5-80 blending amount of thermoplastic polyester to 100 of PPS. The blending amount of modified polyolefin is 5-80, and the blending amount of thermoplastic elastomer is also 5-80, and when the amount exceeds both of the amounts, heat resistance is damaged.
